Then a data transmitting and receiving circuit 20 reads data out of the device 4 and writes the data in a device 5. Thus, the copy control processing part 13 copies the volume while repeating the input/output processing. At this time, if an input/ output request source program 10 sends a write request to the magnetic disk device 4, an input/output control program 11 reads the addresses out of the address storage circuit 12 and an address comparative and decision part 14 makes a comparative decision.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To easily effect a joint treatment at a joint of external wall panel by a method wherein a distance between adjoining supports of a scaffold is set to N (N: an integer) times the module employed as a distance between framing columns so that the support is offset so as not to oppose a joint part of the external wall panel. SOLUTION: Supports constituting a scaffold are disposed in a direction of extension of the scaffold around a building, in which a distance between adjoining framing columns 1 is set to any of distances set to N (N: an integer) times a predetermined module. In the arrangement of supports constituting the scaffold, a predetermined module equal to the predetermined module employed in setting a distance between the framing column 1 is employed. Thus if a support 3a and support 3b each being a certain support are disposed in a direction of extension of the scaffold so as to be offset the predetermined dimension, other supports located in the direction of extension are offset a dimension equal to the predetermined dimension. As a result, a support of the scaffold does not oppose a joint part of the external wall panel so that joints of the panel can be easily treated around the building.
